(CNN) -- Costs for an executive MBA vary enormously, with location, length of course and the perceived quality of the course provider being some of the key determinants.

For example, A 22-month EMBA from the Richard Ivey School of Business at its campus in Hong Kong costs $67,500, while the China Europe International Business School (CEIBS) two-year executive MBA program offered in Shanghai costs about $60,000.

The 14-month offering in Paris from European provider INSEAD costs about $100,000, IMD's 10-week course in Lausanne, Switzerland runs to $44,000 and the 16-month global executive MBA program run by the Barcelona-based IESE Business School is about $80,000.

In the United States, the Katz Business School at the University of Pittsburgh runs an EMBA program for $45,000. In Chicago, 2005-06 tuition and fees for the executive MBA offered by Northwestern University's Kellogg School of Management -- regarded as among the best in the United States-- run to $54,000 a year for two years, for a total of $108,000.

Singapore's Nanyang Business School offers a Chinese-language executive MBA and from next year will have an English version.

Nanayang's EMBA participants can complete some study modules in the U.S. at the University of California's Berkeley business school campus as part of the Advanced Management Program. Fees for the 2005/06 AMP course are set at $27,600 and at about $42,000 for the proposed EMBA.

There are shorter versions of EMBA-style programs. INSEAD runs a two-week course in Singapore that costs $11,000 and a three-week one for young managers in either Singapore or Europe that costs about $19,600.

In the United States, Northwestern University's Kellogg and Duke University's Duke Corporate Education are also among the leaders in "open" and "custom" programs devised for the specific needs of companies. Course costs vary with the length and intensity of the programs.

The University of Pennsylvania's Wharton School runs a five-week advanced management program that costs about $40,000.

In comparison, a full-time two-year MBA from Wharton -- usually ranked among the top U.S. business courses -- costs about $80,000. Harvard, Stanford, Columbia and University of Chicago's Graduate School of Business are about the same.

In the UK, the two-year full-time MBA from the London School of Business is about $65,000. Warwick Business School offers a distance-learning MBA course with UAE partner Knowledge Horizon in Dubai for about $24,000.

In Australia, the University of Melbourne's Melbourne Business School runs a 14-month executive MBA, made up of four one-month intensive modules, at a cost of about $64,000. Its full-time 16-month MBA costs about $35,000.
